摘要： A method for re-allocating memory partition space is provided. The method comprises determining when a first memory partition is full or has reached a threshold value, determining that a second memory partition has unused storage space that can be allocated to the first memory partition, and assigning the unused storage space from the second memory partition to the first memory partition. A memory controller embedded within the mass storage device and having an interface to an external host assigns the unused storage space from the second memory partition to the first memory partition.

摘要： A mass storage memory system and a method for re-allocating memory partition space is provided. The storage system includes a memory controller with a microprocessor that is adapted to receive data via a logical interface from a host system; a first memory partition with a system area and a data area; and a second memory partition with a system area and a data area; wherein the memory controller re-allocates memory space from the second memory partition to the first memory partition that is either full or has reached a threshold value, by using a virtual block address for the system area and the data area such that the system area and the data area appear contiguous to the host system.

摘要： Methods and apparatus for maintaining an average erase count in a system memory of a non-volatile memory system are disclosed. According to one aspect of the present invention, a method for determining an average number of times each block of a number of blocks within a non-volatile memory of a memory system has been erased includes obtaining an erase count for each block that indicates a number of times each block has been erased. Once all the erase counts have been obtained, the erase counts are summed, and an average erase count that indicates the average number of times each block of the number of blocks has been erased is created by substantially dividing the sum by the number of blocks.
